[previous] 0656 [next] [C] Function return type cannot be function or array type, or an incomplete struct/union (for function definition).
Constraint violations REFERENCE - ISO:C90-6.5.4.3 Function Declarators - Constraints, ISO:C90-6.7.1 Function Definitions - Constraints

This is a constraint error

The return type of this function is invalid. It cannot be an array type or a function type and a function cannot be defined with a return type which is an incomplete struct or union type.

For example: 


/*PRQA S 553,1307,2213,2216,3132,3210,3408,3447,3448 ++*/

typedef int TI;
typedef struct {int a; int b;} TS;
typedef int TF(void);
typedef int TA[10];

extern TI f1(void);
extern TS f2(void);
extern TF f3(void);                     /* Message 0656 */
extern TA f4(void);                     /* Message 0656 */
